JAMES C. GILLISPIE, OF WALTHAM, MASSACHUSETTS.

HINGE.

SPECIFICATION forming part of Letters Patent No. 691,620, dated January 21, 1902.

Application filed July 16, 1 01.

To aZZ whom it may concern.-

Be it known that I, JAMES C. GILLIsPIE, residing at Waltham, in the county of Middlesex and State of Massachusetts, have invented a certain new and useful Hinge, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to hinges, being in the nature of a lock-hinge designed for use in connection with blinds, doors, and the like and adapted to hold the blind either open or closed or in any desired intermediate position. a

One of the principal objects of the present invention is to provide in connection with a hinge a movable arm which may be adjusted to any desired angle with respect to the stationary portion of the hinge, so that the blind may be fastened always at the same point previously determined upon. The hinge also embodies a construction by means of which the blind, door, or like article may be easily replaced in position after it has been detached or unmounted from the window or door frame.

To facilitate the disclosure of the invention, the device will be described in connection with and as applied to an outside blind, although it will be apparent as the description proceeds that the improved lock-hinge may be applied to other forms of blinds, doors, and the like without sacrificing any of the advantages of the invention.

With the above and other objects in view the invention consists in the novel construction, combination, and arrangement of parts corresponding parts in all the figures.

For illustrative purposes I have shown the invention applied to a blind, (designated at Serial No. 68,638. (No model.)

v1,).the same being mounted upon a windowupper hinge are disconnected bylow'ering the blind 1 andare reassembled by elevating the blind after having entered the pintle 6 into the knuckle 5. The lower hinge member 3 is likewise provided with a tubular knuckle 8, similar to that, 5, above described. The stationary member of the. lower hinge comprises a base-plate 9, of suitable length, provided at its opposite ends with upstanding lugs 10, each provided at the top with a dropnotch 11, adapted to receive and engage a spring-catch on the blind, hereinafter described. Eachlug10alsocomprisesabeveled or inclined forward edge 12, up which the spring-catch is designedto slide in finding its way to the drop-notch 11. The stationary hinge memberis fastened to the window-sill by means of screws or other suitable fasteners 13, as illustrated in Fig. 1, so that the lugs 10 are located, respectively, at opposite sides of the axis of movement of the shutter, or, in

other words, at opposite sides of the verticalof the shutter being borne by the socket 14,

upon which the knuckle 8 rests, as shown in Fig. 1. is first slid upward over the pintle 6, after which the knuckle 8 is brought to bear on the socket 14, the pintle 15 being then inserted to hold the parts against displacement.

Connected to the bottom rail 16 of the blind is a spring-catch constructed of a piece of sheet metal and comprising a body portion 17, provided with openings 18 to receive fasteners wherewith the catch is fastened permanently to the blind. The body of the catch has extending therefrom a spring-tongue'19, which is recurved, as shown at 20, and ex- In mounting the blind the knuckle 5' Ioo tended forward, so that its free end lies be I neath the body 17, said tongue terminating in an angular downturned catch-lip 21, which is adapted to engage the notches 11 in the lugs 10, hereinabove referred to. In order to facilitate the manipulation of the springcatch, the end portion of the tongue is provided with laterally-extending wings 22,which form finger-pieces, enabling the operator to place one or more fingers beneath the bottom rail of the blind for the purpose of lifting the catch-lip out of engagement with the notched lugs. It will be seen that the lugs 10 are so arranged with respect to the spring-catch that the engagement between the catch and lugs is effected either when the blind is fully closed or fully opened.

In order to fasten the blind in an intermediate position, I-provide a detachable and adjustable arm 23, the length of whichis slightly greater than one-half the length of the stationary hinge member 9. The arm 23 is provided at its outer extremity with a lug 24, having a centrally-located drop-notch 25 and reversely beveled orinclined surfaces 26,upon which the catch-lip 21 is adapted to slide preparatory to springing into the notch 25. At its opposite end the arm is provided with an opening 27, by which the arm is adapted to be fitted over the pintle-socket 14, the latter serving as the pivot about which the arm may be swung in adjusting its angle. The inner end of the arm is expanded or widened to provide for the formation therein of a curved slot 28, said slot receiving a clampingscrew 29, which engages a threaded opening in the base-plate 9 of the stationary hinge member. It will thus be seen that the arm 23 is detachable when not needed in use. When the arm is in use, it may be swung to any desired angle upon the socket It as a pivot and may be securely fastened when adjusted to the desired angle by tightening the screw 29. By means of the arrangement described the blind may be bowed to any desired extent and may also be quickly adjusted to exactly the same angle by fixing the position of the adjustable arm. It will also be seen that there are no intermediate devices between the lug 24 and either of the lugs 10 for engaging the catch-lip while swinging the blind open, so as to engage it with the lug 24. The adjustment of the blind to the desired angle may thereby be instantly efiected, it being only necessary to disengage the catch from one or the other of the lugs 10 and push the blind outward until the catchlip snaps into engagement with the notch in the lug 24.

The lock-hinge hereinabove described is simple and reliable in operation, economical in construction, and may be quickly applied. The hinge members serve to strengthen the frame of the blind, so that the stiles will not pull away from the top and bottom rails. They also prevent the blind from being lifted or detached from the window-frame. The

spring-catches hold the blind tightly in either its open or closed position and prevent all rattling in windy weather. The arm 23 is especially useful when on account of any unforeseen obstruction the blind cannot be thrown all the way open, so as to bring the spring-catch into engagement with the outer notched lug. In such case the arm 23 may be adjusted to a position where it will operate to hold the blind open to the fullest possible extent. Where the blind is capable of being opened all the way, the arm 23 may, if desired, be dispensed with.

I do not desire to be limited to the details of construction and arrangement hereinabove set forth and accordingly reserve the right to change, modify, or vary the construction within the scope of the appended claims.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-

1. A lock-hinge comprising a stationary member and a movable member, the movable member being pivotally connected to the centralportion of the stationary member, notched lugs on the stationary member at opposite sides of the connection between the hinge members, and a spring-catch connected with the blind and embodying a spring-tongue, a terminal catch or lip, and oppositely-projecting wings forming finger-pieces, substantially as described.
